A threshold is a level of service. Below this level, you consider that customers to your contact center do not receive a satisfactory response. Above this level, you consider that your customers have a positive experience. For example, you can set a threshold time for your agents to respond to interactions. If you set this time at 20 seconds and your agents successfully respond to all interactions within this time limit, you might consider this a satisfactory performance. However, if your agents fail to respond to interactions within this time, you might consider adding more agents to your contact center or attempting to divert callers to digital methods of contact.
